GONVEYER.

Specification of Letters Patent.

Patented Mar. 14, 1916.

Application filed August 3, 1914. Serial No. 54,756.

To all whom it may concern:

Be it known that I, AMos D. HERB, a citizen of the United States,residing at Lake Ballinger, in the county of Snohomish and State ofWVashington, have invented certain new and useful Improvements inConveyors, of which the following is a specification.

,This' invention relates to a conveyer and the principal object of theinvention is to provide an improved type of conveyer pipe which is soconstructed that the passage of materials through the pipe will not behindered by the hoods which close the openings through which the steampipes enter the conveyer.

Another object of the invention is to so mount the drums and hand-holdcovers that the same may be removed when desired.

This invention is illustrated in the accompanying drawings, whereinFigure 1 is a view in side elevation showing a conveyer constructed inaccordance with this invention; Fig. 2 is a fragmentary sectional viewthrough the conveyer; and Fig. 3 is a top plan view of that portion ofthe conveyer which is shown in Fig. 2. Fig. 4 is a transverse sectionalview of the pipe.

The conveyer pipe 10 leads from the cyclone 11 and has its free endportion 12 bent downwardly and terminating in an enlarged mouth 13. Thelower portion of the conveyer is provided with openings through whichthe guards or hoods 14 extend, the guards being secured to'the conveyerpipe by bolts 15 so that the guards may be removed when necessary. Theseguards 14: have their forward walls 16 provided with openings throughwhich the nozzles 17 of the steam pipe 18 pass so that steam will beinjected into the conveyer. The upper portion of the pipe 10 is providedwith an opening 19 above each of the guards 1 1 and a second opening 20just forward of the i opening 19. A bell-shaped drum or cover 21 isprovided for the opening 19 and is secured to the pipe by means of bolts23. This cover is formed bell-shaped as shown in Figs. 1 and 2 so thatthe diameter of the pipe will be increased at the point where the hoodor guard 14 is placed, and thus prevent the pipe from being choked. Thepassage of shavings or other matter through the pipe will therefore notbe retarded. The hand-hold 20 which is normally closed by the cover orcap 24 is provided so that when desired, the cap can be removed andaccess easily had to the nozzle 17. This construction will thereforeprovide a conveyer which cannot be easily choked or stopped up and whichis so constructed that when desired, access may be easily had to theinterior of the pipe for the purpose of cleaning the pipe or for anyother purpose.

What is claimed is A conveyer pipe provided with a lower opening, aguard secured to said conveyer pipe and extending through the opening inthe same, a fluid pipe extending through said guard into said conveyerpipe and eX- tending toward the outlet end thereof, said conveyer pipebeing provided with an opening positioned above said guard and with asecond opening positioned adjacent said last mentioned opening andforward of the inner end of said fluid pipe, a convex cover for theopening above said guard, and a cover for the opening forward of saidfluid pipe.

In testimony whereof I affix my signature in presence of two witnesses.
